Services of Communication Systems
FEKT-MPA-SKSAcad. year: 2020/2021
The course deals with services provided by current telecommunication systems. Students obtain essential knowledge of technologies that are used all the time even if not preferably, i.e. ISDN services and Asynchronous Transfer Mode ( ATM). Emphasis is however on current technologies such as xDSL (ADSL, SDSL, HDSL, and VDSL) and on modern transmission connected to the SS7signalling system. Students will significantly deepen their knowledge of Internet protocol version 6 following up on IPv4 and focusing on Quality of Service QoS. They will obtain further information on IP/ATM integration and on LAN emulation. They will also be made familiar with priority control in network elements and with services over power network and cable TV.
Learning outcomes of the course unit
- analyse services provided by contemporary communication networks,
- theoretically analyse the technologies related to xDSL services,
- justify the contemporary state of ISDN usage,
- sum up the features of ISDN,
- compare ATM and other possibilities of high-speed transmission
- explore the creation of ATM cells in relation to services,
- design signalling by means of SS7,
- categorize the Quality of service, QoS,
- explore the potentials of IPv6 in QoS assurance,
- compare the possibilities of routing in network elements,
- plan LAN emulation,
- judge services transmitted over a power network and cable TV,
- practice the MySQL environment,
- configure the Jabber server,
- estimate network safety.
